GITARD-ARM FOB COUPLINGS.

To all whom z'tmay concern:

Be it known that. I, ROBERT E. L. J ANNEY,

a citizen of the United States, and resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Guard-Arms for Couplings, of which the following is aspeci- It is well known that car couplers are sub-' jected to severestrains and that the guard arm receives many of the most severe of thesestrains. It is an object of the present invention to provide areinforcement for the guard arm, the metal being so distributed as toprovide for a maximum efiiciency. Not only is it desirable to providefor the maximum resistance to strain, but likewise for ease in theproduction of the casting. To this end means should be provided forsupporting the cores. If such means are not provided, many faultycastings will be produceddue to theshifting of the cores. The desiredresult as to all these particulars is secured in the structureillustrated herewith.

In the drawings Figure 1 is a side elevation of a car coupler, the viewbeing taken from the guard arm side. I

Figs. 2 and 3 are sectional views taken on the lines 22, 3-3,respectively, of Fig. 4, and Fig. 4 is a plan view'partly in section.

The construction herein I disclosed is intended as an improvement onconstruction of my application, Serial Number 41869, filed July 26,1915. I

In the drawings it will be seen that the coupler-head 10 is providedwith the usual ears 11 and a guard arm consisting of a vertical wall orweb 12, which is suitably reinforced by means of the converging upperand lower webs 13, 14 and-the intermediate horizontal web 15. These websor ribs merge into or join the vertical wall 12 at the extremities ofthe webs. In order to brace and add materially to the effectiveness ofthe converging webs 13, 14, I unite the margins thereof at pointsintermediate the Copies of this patent may be obtained for Specificationof Letters Patent.

Application filed October 14, 1916. Serial No. 125,539.

I for the production of walls the correct thickness. While I haveshownthe webs 16, 17

as extending horizontally, and this is the preferred construction, yetsubstantially the same advantages would accrue if the webs were not soplaced. The object is to provide a brace or strut which will serve toprevent the collapsing or distortion of the converging webs.

It will be understood also that the exact form and arrangement is notessential to the advantageous utilization of the invention and.thatmodifications may .be made therein without departure from thespirit thereof.

I claim:

1. In a guard arm for car couplers, the combination of a vertical wall,converging outer webs, and webs joining the edges of said convergingwebs to said vertical wall, substantially as described.

2. A car coupler guard arm havin a vertical wall, converging outerstrengthening and an intermediate horizontal web, and

stiifening webs joining the edges of said inclined webs to said verticalwall, said stiffening webs being apertured to provide a passage betweenthe. cavity inclosed by said websand the space adjoining said horizontalweb, substantially as described.

Signed at Chicago, Illinois, this 11th day of October, 1916.
